FIREPROOF" PARTITION.

SPECIFICATION forming part of Letters Patent No. 518,050, dated April10, 1894.

4 Application filed December 26, 1893. Serial No. 494,645. (No model.)

To aZZ whom it may concern: 7

Be it known that I, SEBASTIAN G. BRINK- MAN, of New York city, New York,have invented an Improved Fireproof Partition, of which the following isa specification.

This invention relates toa fire proof parti-' tion of simpleconstruction and which is to be used for subdividing lofts and floors,and for forming elevator shafts.

In the accompanying drawings: Figure 1 is an elevation partly in sectionof two partitions that join at right angles. Fig. 2 is a horizontalsection on line 00, 00, Fig. 1, and.

- the bottom and top, the uprights a, are connected by the horizontalchannel irons a, a the top iron being bolted in place after thepartition has been built up. Between the uprights a, there are stretchedhorizontal sheet metal I bars I), the ends of which are received by theuprights and are thus securely held in place. The bars b, are preferablymade in the manner indicated in Fig. 3, in which they are shown to bemade with a web of a single thickness, which is first bent upward andthen downward to form the double heads. Each head is thus composed of aflange made of double thickness, and a flange made of but asinglethickness of metal. order to make the distance between each pairof flanges alike, the free ends I), should be slightly bent inward asshown.

Between the I bars b, there are placed the parallel rows of blocks 0,made of baked clay or other suitable fire proof material, and whichenter with theirupper and lower ends between the flanges of theadjoining I bars.

In order to build up the partition, the frame a, a, a, of channel ironis first erected and the lowermost row of blocks 0, is put in place.-The lower end of this row will enter the groove of the channel iron 0.,while the two flank blocks will enter with their outer ends, the groovesof the irons a. After the lowermost row has been put in place, the firstI bar b, is slipped in between the uprights so as to be confined therebyand to project with its bottom flanges over the upper end of thelowermost row of blocks 0. row of blocks is put in place and the next Ibar is slipped over them and in this way the entire space between theuprights is filled in to complete the partition. At the top, theuprights are finally connected by the channel iron a which engages theupper end of the uppermost row of blocks, and which isobolted to theuprights a, by means of the bolts a to form a compact structure.

The advantages connected with my improved partition are the great easewith which it may be put together, its great stability, and that all itscomponent parts may be fitted in the shop and may then be readily'put inplace, with a minimum amount of bolting or riveting. When two partitionsare to join at right angles to form a shaft, the two adjoining uprightsare simply bolted together.

What I claim is 1. The combination of grooved uprights with horizontal Ibars engagingsaid uprights and with blocks engaged at the top and bottomby the flanges of the I bars, substantially as specified.

2. The combination of grooved uprights with horizontal bars havingdoubled flanges and with blocks engaged by said flanges, substantiallyas specified.

3. A partitioncomposed of flanged uprights, horizontal I beams havingdoubled flanges at one side, single flanges at the other side andinterposed fire proof blocks, substantially as specified.
